Boss Michael Goode called on Deeping Rangers to “put it right” after a below-par display.
They face a trip to Harrowby United on Tuesday night after five games without a win.
The Hinchingbrooke Cup semi-final defeat at home to Peterborough Northern Star was followed by Saturday’s 3-1 loss to Boston Town which ended a five-match unbeaten league run with four draws.
Goode – serving a three-match touchline ban – said: “It was very poor, but not for the full 90 minutes on Saturday.
“We played good football and created little openings. We hit the post and had another ball across the face of goal.
“But then we conceded a soft goal from a long ball behind our defence.
“After that we had three good spells of five minutes and at half-time we talked about playing the ball forward.
“As soon as we equalised, we tried to over-complicate it by over-playing and over-passing by giving the ball away in some ridiculous areas around the penalty box.
“We tried to do things that are outside the comfort zone. We are at this level for a reason and we’re not good enough to play to feet all the time.
“When it’s not going well, you have to work harder but for 90 minutes in the cup game and the second half on Saturday our ethic to win the ball back was not there.”
